Patent JP-H02156612-A (JP)
Title: Transformer device for high-voltage generation
Inventor: SAKAI YASUTAKA
IPC: H01F38/42
Filed: 1988-12-09
Abstract: PURPOSE:To reduce cost by a method wherein a starting end of a winding of a lowest potential layer on the ground side is installed at a ground or between both ends of a winding in another layer, an electrical middle point is formed, a terminating end of a winding of a highest potential layer is situated in an electrical middle point of another layer and an output is taken out from the terminating end of the winding. CONSTITUTION:A terminating end of a winding 10f out of secondary windings 10a to 10f is shifted toward the center by 2/3 from a terminating and (left end) of the other windings. Only a starting end of the winding 10a is shifted toward the center by 1/3 from a starting end (right end) of the other windings. When a sawtooth current flows to a primary winding, starting ends of the secondary windings generate positive pulse voltages. When the starting end of the winding 10a is grounded, the windings 10b to 10e lose their degree of electrical freedom near the starting end of the 10a; their potential with reference to a ground is fixed; a pulse voltage is not generated to the ground; an electrical middle point is generated. When the terminating end of the winding 10f is situated in the electrical middle point of the windings up to 10f, the pulse voltage is not generated here; only a DC voltage is generated at the terminating end. As a result, a rectifier diode or the like for a CRT is not required; the cost can be lowered.

Title: Substrate bias potential generation circuit for semiconductor integrated circuit device
Inventor: KUMANOTANI MASAKI
IPC: H01L27/108
Filed: 1988-12-08
Abstract: PURPOSE:To reduce current consumption by providing two substrate bias generating means with different bias capacity, and operating selectively only either the means corresponding to substrate potential. CONSTITUTION:A substrate potential detector 280 detects the potential of a semiconductor substrate, and supplies an output signal to bias potential generation circuits 10 and 20. The bias capacity of the circuit 10 is comparatively low, meanwhile, the circuit 20 is provided with comparatively high bias capacity. In a bias state with low substrate ionizing potential, the circuit 20 is operated by the detecting output of the detector 280, and substrate potential is lowered steeply to a prescribed level. When it arrives at the prescribed level, the circuit 10 is operated, and it keeps the substrate at the prescribed level. In such a manner, the current consumption can be reduced by operating only either the circuit 10 or 20.

Title: Continuously variable transmission for vehicle
Inventor: TANIGUCHI KATSUHIKO
IPC: F16H47/06
Filed: 1988-12-10
Abstract: PURPOSE:To prevent a belt from slipping when a vehicle reverses by controlling the line pressure working on a pulley when a vehicle reverses with the reverse rotation of an impeller to be higher than the line pressure for forward movement with the turbine impeller rotation in the normal direction. CONSTITUTION:When a brake mechanism 42 engages with a brake side casing 60, a direct engagement clutch 62 engages with the brake mechanism 42 in linked motion and the rotation of a stator impeller 44 is stopped. As a result, oil flow is reversed with the blade of the impeller 44 and oil flows in from the back side of a turbine impeller 48 and the impeller 48 rotates in the opposite direction to that of a pump impeller 40. At the time a vehicle reverses with the reverse rotation of the impeller 48, a line pressure PR to be exerted on a drive side pulley 4 for example is made higher by a specified value than a line pressure PF for the forward movement of the vehicle with the normal rotation of the impeller 48. This makes it possible to prevent a belt from slipping even if a torque difference is produced at the time of forward or reverse movement with a torque converter 50 by compensating the torque difference with the line pressure.

Abstract: PURPOSE:To make it possible to detect an input brightness component as accumulating histogram by installing a plurality of compare circuits for comparing specified values different from an input brightness signal, and by installing a plurality of counters for counting the output from each compare circuit. CONSTITUTION:Assuming that the magnitude of an input brightness signal is 100, the output from the first compare circuit 11, since the magnitude of the input brightness signal is greater than a compare value of 64, outputs 0, while since the magnitude of an input brightness signal to the 2nd compare circuit 13 and that to the 3rd compare circuit 15 are both greater than their respective compare values, both the 2nd and 3rd compare circuits output 1, respectively. Accordingly, the 1st counter 12 does not carry out countup operation, while on the contrary the 2nd and 3rd counters 14 and 16 carry out countup operation. When this sampling is repeated 256 times, although the histogram for a brightness level of 256 is not taken here, since a value of 256 is higher than magnitudes of all the input brightness signals, the number of times of sampling automatically turns to 256, and by connecting 0, the output from the 1st counter 12, the output from the 2nd counter 14, the output from the 3rd counter 16, and 256, an accumulating histogram can be obtained.

Title: Retrofocus type lens
Inventor: SATO HARUO
IPC: G02B13/18
Filed: 1986-12-24
Abstract: PURPOSE:To suppress aberration correction at a close distance by introducing an aspherical surface, which has a property to prevent the degradation in performance at a close distance mainly, into a rear group of the second lens group having a focusing function. CONSTITUTION:A second lens group consists of a front group G2F and a rear group G2R which has a positive refracting power and the focusing function. The rear group of the second lens group has a spherical lens having at least one aspherical surface, and the aspherical lens has such shape that a negative surface refracting power is increased according as going toward the periphery from the apex. A stop is arranged on the object side of the aspherical lens in the rear group G2R of the second lens group, and the rear group G2R of the second lens group is fed out to the object side along the optical axis to focus this lens system to an object at a close distance. Thus, a positive refracting power to oblique rays is not very varied as the whole of the focusing group though aberrations are preliminarily corrected and the height of incidence to oblique rays is changed as usual as the whole of the focusing group G2R, and the variance of coma is suppressed as much as possible.
